A user asked how they could restore the default security settings for NT files and directories. Doing so is easy, provided you've got a copy of the NT Resource Kit handy. In the Resource Kit you'll find a tool called FIXACLS.EXE. The tool will reset NT's file and directory permissions based on the permission definitions located in the PERMS.INF file. The PERMS.INF file is located in the %SYSTEMROOT%\INF\ directory and contains a list of default permission settings for use with the FIXACLS tool
